abstractText | Targeted immune regulation can be achieved by use of tissue-specific T cells and offers the potential for organ-specific suppression of destructive autoimmune processes. Here, we report the generation and characterization of insulin B chain-specific 'autoreactive' CD4+ regulatory T cells that locally suppress diabetogenic T cell responses against an unrelated self-antigen (viral transgene) in a virus-induced model for type 1 diabetes. Interleukin 4 (IL-4) is essential for prevention of diabetes since regulatory T cells cannot be induced in the absence of IL-4 or stat6 (IL-4 signaling pathway). Our observations demonstrate that autoreactive regulatory T cells can suppress autoreactive destructive T cell activity of differential antigenic specificity locally in the pancreatic draining lymph node, probably via cytokine-mediated modulation of antigen-presenting cells. |
